Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 64

A minimal faithful permutation representation — 4 generators on 28 points:

(2,3)(5,6)(7,9)(8,10)(11,12)(13,14)(15,17)(16,23)(18,22)(19,25)(20,26)(21,27)(24,28);(1,2,4,3)(5,7)(6,9)(8,12)(10,11)(13,15,17,14)(16,21,24,19)(18,22,26,20)(23,25,28,27);(5,6)(7,11,12,9)(8,10)(13,16,18,25,17,24,26,27)(14,19,20,23,15,21,22,28);(1,3,4,2)(14,15)(19,21)(20,22)(23,28)
